Web Development for UK Startups & SMBs
MicroPyramid is a web development company that builds custom web applications, SaaS products, dashboards, and APIs for UK founders and engineering teams, using Django, FastAPI, React, and SvelteKit, with AI-assisted engineering that gets a first working release live in weeks, not months.
Why UK Teams Choose Us for Web Development
Three reasons UK founders and product teams pick MicroPyramid over a local agency or a generic offshore team
Privacy-Aware and WCAG 2.2 Accessible
We design data protection into the architecture from the start, and build with WCAG 2.2 accessibility baked into frontend work, the standard UK public-sector and enterprise buyers expect. AWS eu-west-2 (London) available for UK data residency.
GBP Billing via Stripe or GoCardless
Invoices in GBP, collected via Stripe or GoCardless Direct Debit. No currency conversion headaches, no wire-transfer friction. Billing that fits how UK businesses actually operate.
Direct Ownership, Not a Ticket Mill
Our engineers directly own every web engagement. You will not be passed to a delivery layer of junior developers. The engineer who scopes your application in discovery is the one who builds it.
Web Development Services for UK Businesses
Six services covering the full web stack, from UK-focused web apps and APIs to accessible frontends and London-hosted deployment
Custom Web Applications
Bespoke web applications built around the exact workflows your UK business runs on: customer portals, internal tools, booking systems, and SaaS platforms. No off-the-shelf compromises, no plugin sprawl.
- SaaS platforms and dashboards
- Customer and client portals
- Internal and admin tooling
Frontend Development
Fast, accessible frontends in React and SvelteKit, built with WCAG 2.2 accessibility in mind, important for UK public-sector and enterprise buyers. Clean, trustworthy interfaces that UK SaaS and proptech users expect.

- Responsive, mobile-first UX
Backend & API Development
Reliable backend systems and APIs using Django, Python, and FastAPI, hosted on AWS eu-west-2 (London) when UK data residency matters. REST and GraphQL endpoints built for real integration loads.
- REST and GraphQL APIs
- Third-party and payment integrations
- Privacy-aware data modelling
Progressive Web Apps
App-like web experiences that load instantly, work offline, and run across every device, no app-store gatekeeping. Ideal for UK SaaS and ecommerce teams who want reach without two native codebases.
- Offline support and caching
- Installable, app-like experience
- Push notifications and fast loads
Security & Performance
Enterprise-grade security and performance work: audits, hardening, and Core Web Vitals tuning. Built for UK organisations that face security questionnaires and enterprise procurement reviews.
- Security audits and hardening
- Performance and Core Web Vitals tuning
- Load testing and monitoring
Cloud Deployment & Hosting
Deployment and managed hosting on AWS eu-west-2 (London) with automated CI/CD pipelines. UK data residency, predictable scaling, and infrastructure that does not wake you at 3am.
- AWS eu-west-2 (London) hosting
- Docker and automated CI/CD
- Auto-scaling and observability
Best Fit For
- UK proptech, SaaS, ecommerce, and agency teams building real web applications
- startups and SMBs that need frontend, backend, and hosting to move together
- rebuilds where privacy-aware architecture and WCAG 2.2 accessibility matter from day one
- projects that need an external partner to own delivery, not just a list of tickets
Not the Right Fit When
- a quick brochure site that an off-the-shelf template or page builder would cover
- engagements looking only for staff augmentation without delivery ownership
- projects blocked mainly by legacy rescue or migration risk rather than new web delivery
- teams adding AI as a slogan rather than a concrete feature inside the web product
If the next step is an AI workflow inside the app, see AI Feature Development. Rescuing a legacy codebase? See Modernization & Upgrades.

Straight answers to what UK founders and CTOs ask us before starting a web project: cost in GBP, timelines, data protection, WCAG 2.2, and who owns the code.
What drives the cost of web development in the UK?
Cost is driven by scope, the number and depth of integrations, overall complexity, and requirements such as data protection, WCAG 2.2 accessibility, and data residency. Rather than quote blind, we start with a fixed-scope Discovery Sprint billed in GBP that gives you a concrete estimate, timeline, and architecture plan before you commit to a full build.
How long does it take to build a web application?
It depends on scope: the number of user flows and roles, the integrations, and how much existing code or data we inherit. A focused first release is the shortest path and larger platforms take longer. The discovery sprint ends with a fixed estimate and timeline, so you know before committing to the build.
How do you handle data protection and UK data residency?
We design data protection into the architecture rather than bolting it on afterwards: personal data kept to what the product needs, access controls, and an audit trail on sensitive records. When UK data residency matters, we host on AWS eu-west-2 (London) so your data stays in the UK.
Do you build to WCAG 2.2 accessibility standards?
Yes. We build frontends to WCAG 2.2 (typically Level AA), the standard UK public-sector and enterprise procurement teams check for. Accessibility is part of the build from day one, not a later audit.
Who owns the code and intellectual property?
You do. You retain full ownership of all source code, IP, and infrastructure we build, and we deploy to your own cloud accounts. We sign NDAs and IP-assignment agreements before work begins. There is no vendor lock-in.
Can you bill in GBP?
Yes. We invoice in GBP and collect via Stripe or GoCardless Direct Debit, no currency-conversion friction or international wire hassle. Engagements are structured as a fixed-scope Discovery Sprint, a fixed-scope build, or a monthly retainer, whichever fits your stage.
Can you add AI features to our web application?
Yes. We embed retrieval-backed (RAG) search, in-app copilots, and AI assistants directly into web products (grounded in your own data, with citations and safe fallbacks), so the features are genuinely useful, not a bolt-on gimmick.
